4K advice

I am starting a new job this Monday. They have ordered me two 4K monitors (Dell 24") and a fully loaded 15" MacBook Pro. Assuming all have arrived by Monday, not a sure thing, the IT department tells me that in order to have both monitors running at 60Hz we will run one through the HDMI port and the other monitor through a Thunderbolt port (mini display port) with a converter to HDMI. Will it work? Dunno. The proof of the pudding is in the eating and all that. I'll post what we find out once I know more.

Hope this helps.

The 15 with 750M can do:
1 4k at 60hz over thunderbolt
1 4k at 30 hz over hdmi (or a 2k screen at 60hz)
Internal screen

Interesting. But what if I run the laptop in clamshell mode -- no internal monitor. Does this free up enough bandwidth to run the second monitor at 60Hz rather than 30?

Also, does it make a difference if I run the two 4K monitors at "best" resolution rather than in native resolution?

I dunno, but folks hate to waste a beautiful retina screen by putting into clam shell mode.

4K monitors

It's a tough call. The 24" monitors should yield Retina Display quality, but I'll have to see it up close and personal before I can give a definitive opinion. Even then, these things are always subjective. I can, however, objectively relate whether or not it is possible to run two 4K monitors at 60Hz (albeit using the "best display" option).

"Some" folks might. I have a dual setup (3840x2160 @ 60Hz and 3440x1440 @ 60Hz) and my rMBP is almost always in clamshell, except when I have to take it with me. Depends on your needs and your setup.

Yeah, I find the laptop screen to be a nice third screen for anything text or menu driven. Seems to be so much easier on the eyes.

My laptop sits on the keyboard pull out shelf which makes the top edge of its screen even with the bottom edge of external monitors on the desk. A nice set up.
